来自隐藏U(1)的特定暗物质特征

Specific Dark Matter signatures from hidden U(1)

Yann Mambrini

摘要:

有几种结构激发了暗$U(1)_D$规范玻色子的存在,它只通过动力学混合或环诱导过程与标准模型相互作用。我们描述了两个典型的例子,具体的签名,特别是我们表明,一个区域相对较轻的WIMPS,$M_{Z_D}\lsim 40$ GeV和动力学混合$10^{-4} \lsim δ\lsim 10^{-3} $还没有被排除在最后的实验数据,似乎在不久的将来给有希望的信号。我们还表明,从异常抵消条件产生三矢量耦合$Z_D Z γ$导致一个特定的伽马射线线观测费米望远镜。

英文摘要:

Several constructions motivate the existence of a dark $U(1)_D$ gauge boson which interacts with the Standard Model only through its kinetic mixing or loop induced processes. We describe two typical examples with specific signatures in particular we show that a region with relatively light WIMPS, $M_{Z_D}\lsim 40$ GeV and a kinetic mixing $10^{-4} \lsim δ\lsim 10^{-3} $ is not yet excluded by the last experimental data and seems to give promising signals in a near future. We also show that conditions from anomaly cancelation generate tri-vector couplings $Z_D Z γ$ leading to a specific gamma ray line observable by FERMI telescope.
